Perfect for ESB and cask ales, YF-109 emphasizes malt and caramel flavors. Its easy flocculation ensures clarity, while the naturally higher diacetyl content adds character to the beer’s body. This yeast is a favorite among traditional English brewers seeking rich, malty depth without sacrificing drinkability. It enhances caramel, toffee, and light fruity notes, producing a comforting and approachable beer. Its predictability makes it ideal for consistent results in pub-style ales.
